GigaBit Laser Driver（GBLD）是一款耐辐射ASIC，旨在以高达5 Gb/s的数据速率驱动边缘发射激光器和VCSEL。它是GigaBit收发器（GBT）和Versatile Link项目的一部分，该项目正在设计一种能够在典型HEP实验的辐射环境中运行的双向光学数据传输系统。GBLD可提供高达24 mA的激光二极管调制电流和高达43 mA的激光偏置电流。实现预加重和去加重功能，以补偿高外部容性负载和非对称激光响应。该芯片采用0.13 μ mCMOS工艺设计，采用2.5V单电源供电，可通过I2C接口编程。
The GigaBit Laser Driver (GBLD) is a radiation tolerant ASIC designed to drive both edge emitting lasers and VCSELs at data rates up to 5 Gb/s. It is part of the GigaBit Transceiver (GBT) and Versatile Link projects, which are designing a bi-directional optical data transmission system capable of operating in the radiation environment of a typical HEP experiment. The GBLD can provide laser diode modulation currents up to 24 mA and laser bias currents up to 43 mA. Pre- and de-emphasis functions are implemented to compensate for high external capacitive loads and asymmetric laser response. The chip, designed in a 0.13 μm CMOS technology, is powered by a single 2.5 V power supply and can be programmed via an I2C interface.
